Tick pheromones
WebbTick pheromones that regulate assembly, attraction/aggregation/attachment, and mating behavior have been described. Most of the compounds regulating these behaviors are purines, substituted phenols, or cholesteryl esters. Other pheromonal compounds … WebbCO2 was absolutely necessary to activate ticks, including the larvae. In addition to activation, our data suggested that CO2 itself is attractive for ticks. The reactivity of the ticks varied greatly with the period of the year, the adults being insensitive to CO2 alone or combined with pheromones for a period extending from December to June.

After 1 h of trapping, 55, 68 and 81% of the active nymphs, males and females, respectively, had reached the trap. Synthetic pheromones (methyl salicylate, o-nitrophenol and nonanoic acid in the proportions 1:2:8) or freshly detached males added to CO2, greatly increased the efficacy of the CO2 traps.
WebbPheromones were first described in ticks by Berger et al. (1971). Berger (1972) subsequently identified the tick pheromone as 2,6-dichlorophenol and characterized it as a sex pheromone. Berger's (1972) pioneering discovery stimulated extensive new research into the occurrence and biological role of tick pheromones.
